Monolithic Vs Microservices

Monolithic Vs Microservices

Monolithic: This type of application generally consists of a single codebase, developed and deployed as a single codebase. Its code, configuration, repositories, and data are kept in a single place. Also, this type of application is easy to develop and maintain because everything is present in the same place. But these are less scalable.

To deploy the Monolithic application, directly the code can be published into the server . For example: consider the IIS web server to deploy the .Net applications and with the help of Azure DevOps, we can follow the CI/CD (Continuous Integration & Continuous Development ) process to deploy the applications by creating the pipeline setup process for the single repo project.

On the other hand, Microservices are completely different from the Monolithic types, In the Microservices architecture the application is completely loosely coupled, and contains multiple repositories for the codebase, multiple configuration files, and multiple services, each service will connect to the same or different database depending on the project needs.

How the Microservices are deployed? As we say the Microservice application consists of multiple codebases to maintain the different services, hence traditional deployment process won’t work due to its complex configuration so here Docker came into existence with the help of Docker each service is containerized into images in order to deploy them.

Docker is a platform that allows you to package and run applications in containers. Containers are isolated from each other and from the underlying host operating system, so they are more portable and efficient than traditional virtual machines.

When you build a microservices application with Docker, you can use Docker images to create a consistent development environment for your team. This means that everyone on your team will be using the same versions of the software dependencies, which can help to prevent errors and improve debugging.

with the availability of Docker on the could platform, it also supports for CI/CD process on Azure DevOps — setting up the .yaml file for the pipeline, creating stages for deployment, setting the branch to deploy, deploying the Docker image to Azure Container Registry,

With the help of Docker:

  • Build images: Docker images are a lightweight, standalone, executable package of software that includes everything needed to run an application: code, runtime, system tools, system libraries, and settings.
  • Run containers: Docker containers are lightweight, standalone, executable units of software that package up code and all its dependencies so the application runs quickly and reliably from one computing environment to another.
  • Deploy applications: Docker can be used to deploy applications to production environments, such as Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
  • Manage applications: Docker can be used to manage applications in production, such as rolling out updates, monitoring performance, and troubleshooting problems.

The best choice of application architecture depends on the specific needs of the project. Monolithic applications are a good choice for projects that are small, simple, and have a limited budget. Microservices applications are a good choice for projects that are large, complex, and require scalability and flexibility.

When to choose Monolithic or Microservices?

  • Team size: Monolithic applications are a good choice for small teams, while microservices applications are a good choice for large teams.
  • Budget: Monolithic applications are a good choice for projects with a limited budget, while microservices applications can be more expensive to develop and maintain.
  • Time to market: Monolithic applications can be developed and deployed more quickly than microservices applications.
  • Scalability: Microservices applications are more scalable than monolithic applications.
  • Flexibility: Microservices applications are more flexible than monolithic applications.

Real-time projects that are currently using the Microservices architecture pattern:

Netflix, Amazon, Spotify, Walmart, and Uber.
